VectorChief/UniSIMD-assembler

Implementations of SIMD instruction sets for systems which don't natively support them.

Low level generic SIMD wrapper for x86, ARM, WASM with dynamic dispatch

Performance-portable, length-agnostic SIMD with runtime dispatch

Portable wrapper for SIMD and vector instructions written in C++11. Compatible with NEON, SSE, AVX, AVX-512 and SVE (length specific).

The platform independent header allowing to compile any C/C++ code containing ARM NEON intrinsic functions for x86 target systems using SIMD up to AVX2 intrinsic functions

C++ wrappers for SIMD intrinsics and parallelized, optimized mathematical functions (SSE, AVX, AVX512, NEON, SVE, WebAssembly, VSX, RISC-V))

The Dlang SIMD library

Keystone assembler framework: Core (Arm, Arm64, Hexagon, Mips, PowerPC, Sparc, SystemZ & X86) + bindings
